The people who have changed their process to control oxygen pickup have experienced the change in beer quality. Just like the first time you use precise temperature control, water chem, control mash and boil ph, etc. All of these little things make up a quality beer. I would actually say the oxygen pickup is a significant factor both in hazy ipa and blonde ale. To achieve this requires the purchase of some equipment, no way around it.
I would agree with the above, if you aren't willing to buy some additional equipment I would skip the secondary. You don't have to worry about yeast off flavors. Give that thing 3 to 4 weeks at 50 degrees (if using lager yeast) and then a week at 62. Bottle and don't worry about extreme clarity. You're beer will be better 100% guaranteed
